anonymous mmap() and random heap allocation
It seems mmap() can not do random allocation for malloc()/heap on Linux, anyone used pax's 'mmap randonness' option for that? what's the price for that? I want to port openbsd's malloc() to linux to avoid heap crashes(overrun/underrun), openbsd's malloc() can do random allocation for security reasons, meanwhile ... 16 Jul 2010 09:54

[PATCH] cpuidle: extend cpuidle and menu governor to handle dynamic states
On some SoC chips, HW resources may be in use during any particular idle period. As a consequence, the cpuidle states that the SoC is safe to enter can change from idle period to idle period. In addition, the latency and threshold of each cpuidle state can vary, depending on the operating condition when the CPU b... 15 Jul 2010 17:38

[PATCH] sched: No need for bootmem special cases
As of commit dcce284 ("mm: Extend gfp masking to the page allocator") and commit 7e85ee0 ("slab,slub: don't enable interrupts during early boot"), the slab allocator makes sure we don't attempt to sleep during boot. Therefore, remove bootmem special cases from the scheduler and use plain GFP_KERNEL instead. Cc... 15 Jul 2010 16:31
